Product Details
Product Introduction
Our Contact Tips are manufactured through precision stamping and forming processes using high-quality silver alloy materials (AgZnO, AgNi, AgSnO₂In₂O₃, AgSnO₂, AgCu, AgSnO₂/Cu, AgCuO/Cu, AgCuO). Each tip delivers stable contact resistance, high electrical conductivity, and excellent resistance to welding and arc erosion. With a monthly capacity of 15 tons and proprietary automation that produces 0.1A–4000A-rated contacts, our tips serve as the critical switching element in contactors, circuit breakers, intelligent switches, and temperature controllers for industrial and commercial applications.
